Oase AquaMax Eco Premium Filter Pump

This pump keeps pond water moving through your filter reliably, and its built-in Environmental Function Control helps protect it from damage if it ever runs dry or picks up a blockage, so a lapse in maintenance is less likely to cost you a replacement pump. It suits pond owners with anything from a modest garden pond up to a large or swimming pond, since it comes in six sizes with maximum flow rates between 5,000 and 21,000 litres per hour. Bear in mind it's supplied without a plug, as UK rules stop manufacturers fitting an indoor plug to fixed outdoor equipment, so you'll need to sort the outdoor-rated wiring yourself.

Overview

The Oase AquaMax Eco Premium is a German-engineered pond filter pump built with a patented second connection point, so you can plumb in an optional filter accessory to pull debris from a second, more distant part of the pond as well as through the main line. Environmental Function Control (EFC) helps protect the pump from damage if it ever runs dry or a blockage builds up at the inlet, which takes some of the risk out of the odd missed maintenance check.

It's aimed at pond owners running a filtration system of any real size, from a small garden pond up to a large or swimming pond, since the range spans six flow rates. The controls are straightforward, and when it's installed dry alongside a swimming or natural pool it runs quietly enough not to be a nuisance.

Key benefits

• Patented second connection lets you feed debris from a second pond zone into an optional filter accessory, alongside the main inlet
• Environmental Function Control helps protect the pump against damage from dry running or a blocked inlet
• Runs quietly enough for dry installation beside a swimming or natural pool
• Moves plant debris and fish waste through the system without constant pre-filtering
• Output can be adjusted electronically once you fit the optional In-Scenio Dimmer or FM-Master 3/FM-ProfiMaster control
• Seasonal Flow Control (SFC), which Oase list for models 12000-20000, regulates the water flow rate and delivery head, and Oase state that switching it on can save up to 30% energy
• Rated to withstand outdoor temperatures down to -20°C

Choosing your size

All six models share the same design and EFC protection; what changes is the maximum flow rate and the price. Each model takes its name from its maximum flow rate in litres per hour (L/h), a pattern confirmed for the 5,000 model:

• 5,000: up to 5,000 L/h, 4.5m maximum head height, 10-35W power draw, the smallest and least expensive model here
• 7,000: up to 7,000 L/h
• 9,000: up to 9,000 L/h
• 13,000: up to 13,000 L/h
• 17,000: up to 17,000 L/h
• 21,000: up to 21,000 L/h, the largest and most powerful model in the range

Power draw and maximum head height for the 7,000 model upwards aren't given in our data, so if a specific lift height or wattage budget matters to your setup, check this before ordering anything above the 5,000.

What's included and installation

What you receive is the pump itself, supplied without a mains plug: UK law bans manufacturers from fitting an indoor 3-pin plug to a fixed outdoor appliance, so wiring it to a suitable outdoor-rated plug or connection is down to the installer. The optional In-Scenio Dimmer and FM-Master 3/FM-ProfiMaster accessories, needed if you want electronic control over the output, are sold separately and aren't part of the box.
